Run x server (xorg xinit) on a headless raspberry pi in DISPLAY=:0

Install the minimum

sudo apt update && \
sudo apt install xvfb x11vnc xinit tightvncserver && \

We start Xorg server through Xvfb

printf "[Unit]\nDescription=xvfb custom\nAfter=multi-user.target\nStartLimitIntervalSec=0\n\n[Service]\nType=simple\nRestart=always\nRestartSec=1\nUser=pi\nExecStart=/usr/bin/xinit -- /usr/bin/Xvfb :0 -screen 0 1360x768x24\n\n[Install]\nWantedBy=multi-user.target\n" | sudo tee /etc/systemd/system/xvfb.service && \
sudo systemctl enable xvfb.service && sudo systemctl start xvfb.service \

We need to put something in the .initrc

Example

sudo apt install openbox tint2 firefox && printf "firefox -width 1360 -height 768 &\ntint2 &\nopenbox" > ~/.xinitrc
